Obsession with precision
We work on modified Centrimaster, Unior and Park Tool centring machines.
The standards we adhere to when truing are 0.15 mm lateral run-out and 0.25 mm radial run-out. However, even the highest precision truing is worth little if the spoke tension is not correctly aligned. We use P&K Lie strain gauges to verify this, which we calibrate regularly on a master gauge we have built. This ensures that the spoke tension is equal and that its absolute values are correct. We align the tension with a tolerance of 10% for the spokes on one side of the wheel. Higher precision is not possible due to imperfections in manufacturing the individual components.
We pay particular attention to stabilising the wheels so that they remain straight throughout their service life.
We use a series of procedures to ensure that “stacking” the spokes takes place in our workshop under controlled conditions. After assembly and tensioning, the wheels are subjected to several stages of expansion on a pneumatic press and re-truing. The loading and truing process is repeated as many times as necessary to achieve balance. We do not recognise shortcuts, so we do not use glue for the spoke threads. Instead, we use the opposite solution – lubricate them thoroughly so that the wheels can be trued in the future.
In addition to constructing wheels from our regular range, we also assemble wheels from components provided by you.
We like challenges, so we are happy to lace unusual spoke wheels for various vehicles, including tandems, rickshaws, wheelchairs, catering trolleys and electric bikes. We have a specialised, well-equipped workshop and the knowledge and experience to realise unique projects.
We like to share our knowledge and are happy to reveal the details of the wheel building process in our workshop.
We are not afraid to share the know-how we have built up over the years; on the contrary, we count on other mechanics to improve their competence by reading the content we share. We are creating a wheeling culture and demystifying marketing nonsense so riders can make the most informed choices when buying equipment. We encourage you to follow our blog, where we discuss various bike wheel issues.
